added modified checks.json which checks for list of classes in wireframe
added tests to check behavior of cheerio to ensure the instance in the callback of loadURL is correct
tested passOutput function which wraps up checkJson and outJson for use in both sync and async cases
working loadURL, troubles with changing cheerioHtmlFile into async version, encapsulated passOut but need to get it working in callback, need if statement to launch depending on options
added logic to tell if user has selected -u option to run different code from -f, still need to fix validation of url data
